The dyeing and printing steps are optional and may be performed as desired in order to provide the velvet plush article with a particular color and pattern.

As shown in FIG. 2, the velvet plush article 10 has a flat body 12 having a middle layer 16 defining a top surface 18 and a bottom surface 20, and at least one a pile layer 22 comprising a plurality of pile hairs 24 extending from the middle layer 16 on the top surface 18, the bottom surface 20, or both. The velvet plush article in the illustrated embodiment 10 has two pile layers 22 on each of the top surface 18 and the bottom surface 20 respectively and the pile hair 24 is uni-directional in which a direction of the pile hair 24 at a frontward direction is the same as a direction of the pile hair at a backward direction in that the direction of the pile hair 24 from a frontward direction is the same as the direction of the pile hair from a backward direction. The According to the invention, the velvet plush article 10 is made of comprises synthetic materials such as polyester and the two pile layers 22 on the top surface 18 and the bottom surface 20 provide a highly smooth and soft touch and feel to a user. In addition, a color 14 and/or a pattern 16 can be provided on one or both of the two pile layers 22 on the top surface 18 and/or the bottom surface 20 as seen in FIG. 1. The velvet plush article 10 can also be manufactured as a velvet plush blanket or a velvet plush sheet for further processing.

As shown in With reference again to FIG. 3, the method of manufacturing a velvet plush article comprises the steps of:

• • (A) weaving a greige cloth by interweaving face yarns and backing yarns, wherein the face yarns are selected from a group consisting of single-ply bright trilobal yarns having linear mass densities of 75D/144F, 90D/144F, 100D/144F or 150D/288F and two-ply yarns having linear mass densities of 120D/288F or 300D/574F, wherein the backing yarns are selected from fully drawn yarns having weights of approximately 68D-100D or draw textured yarns having weights of approximately 100D-150D;

  • (C) dyeing the preprocessed greige cloth to form a colored greige cloth; and
  • (E) finishing by sequentially softening, drying, brushing, stentering, heat-setting, singeing, shearing and final heat-setting the colored greige cloth.

Alternately, after the step (B) or (C), the method of manufacturing a velvet plush article further comprises the steps of:

• • (D) printing the pre-processed greige cloth obtained from step (B) or printing the pre-processed and colored greige cloth obtained from step (C) to form a printed greige cloth; and
  • (E) finishing by softening, drying, brushing, stentering, heat-setting, singeing, shearing and final heat-setting the colored or printed greige cloth sequentially.

Preferably In one embodiment of the invention, in step (A), first and second filaments the face yarns and backing yarns are provided in a ratio of 4:1, wherein the first filament is a backing filament.

In step (B), in one embodiment of the invention the brushing involves brushing in a frontward direction and in a backward direction as shown in FIG. 3A; the first setting involves heat-setting at 120-130° C. at a rolling speed of 25 m/min; as shown in FIG. 4, the singeing involves a sequential rolling for six times at a frontward, backward, backward, frontward, backward and backward directions singe rolling performed by passing the greige cloth F in frontward, backward, backward, frontward, backward and backward directions sequentially across hot rollers R; and the second setting involves heat-setting at 170-180° C. at a rolling speed of 25 m/min.

In step (C), dyeing the greige cloth includes bathing in dye fluid and rinsing with water as shown in FIG. 3B. In one embodiment additional dyeing time of 20 minutes is required due to immersion of the greige cloth in a water bath having a neutral pH or the lowest acidity that will result in a smooth and bright surface.

in step (D), printing includes the steps of brushing in a frontward direction, setting at 150° C. at a rolling speed of 25 m/min, and printing a preset pattern.

In step (E), softening includes washing to add acidity until the greige cloth is soft and then neutralizing the pH of the greige cloth as shown in FIG. 3C. If the pH is lower than 7, the fiber density of the greige cloth will diminish. If the pH is greater than 7, the greige cloth will be hardened; drying includes drying under 190° C. at a rolling speed of 20 m/min with an upper drying channel operated at 300 rpm and a lower drying channel operated at 1200 rpm; brushing includes brushing two brushing cycles; stentering includes stentering in a frontward direction and a backward direction as shown in FIG. 3D; heat-setting includes heat-setting under 150° C. at a rolling speed of 25 m/min with soft air; singeing includes passing the greige cloth across a plurality of hot singe rollers in frontward and backward directions, and preferably, as shown in FIG. 5, includes passing the greige cloth F across hot singe rollers R in backward, backward, frontward, frontward, backward, frontward, backward and frontward directions sequentially; shearing includes shearing in frontward, backward, backward, frontward, frontward, frontward, backward and backward directions sequentially, as shown in FIG. 3E, such that the final orientation of the pile hair is the same when approaching the cloth in both frontward and backward directions; and final heat-setting includes heat-setting at 190° C. at a rolling speed of 30 m/min.

There have thus been described and illustrated certain embodiments of a method of manufacturing velvet plush according to the invention. Although the present invention has been described and illustrated in detail, it should be clearly understood that the disclosure is illustrated only and is not to be taken as limiting, the spirit and scope of the invention being limited only by the terms of the appended claims and their legal equivalents.
